Now Robusta coffee is cultivated mainly in West Africa and Southeast Asia. Robusta tree is growth plant at low elevations (sea level to 600 m), moisture resistant and more resistant to disease than Arabica coffee. Robustas mature in about half time required Arabica coffee and produces almost twice as much coffee fruit.
Unlike Arabica beans, Robusta beans not fall from the tree when cook, so they doesnt need to immediately harvest. Robustas also used for commercially canned coffee and instant coffee. Because cheaper cost of production, Robustas sometimes combined with Arabica coffee to get the strong coffee aroma as well as low levels of caffeine.
